IMPROVEMENT IN BARRELHEADS AND TAPS.

The Schedule'xeferxed to in these L etters Patentv and. part of the same.

other Liquids; and we hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompany and form a part of these specications, in which- Figure' 1 is a plan view of the cask 'or barret-head, from without. Figure 2, sectional view, cut at right angles .to the plane of the disk forming the head.-

Figure 3, plan of the head, from within the cask.

its interior parts.

Letter A, metallic head, and, if made of iron, is to be coated with zinc or' tin.

Letter B is Ithe bung by which the cask is filled, dispensing with the bung iii the bilge. Letter 0the tap whence the liquor is drawn from the cask. This tap consists of the cap l, the yoke e;

the spring f, 'and key g.

Letter C 'is a tap, the same as Q, only placed in the bung B', `and thus obviates'the use of the oke e, and the necessity of making a separate, attachmentfor it in the ,hea/dA, asis th'ecasein fig. 2.

Letter B is a bung, with the tap within it, as just above mentioned, and, when this is used, the separate tap C and the bung B may .bedispensed with.

The cash-heads A, when made of metal, lare cast,

and a bung-opening, with female screw, east therein,

'and the'corresponding male screw is cast upon the bung itself, and forms a' part thereof, being moulded at the same time and with the body of the bung.'

and` at the same tmewith the said key; and, in the `g in the head A.

This plan of structure. is adopten use the yokee, as in ig.-4.

` ...By turning this piece S further in, thecask will be s made toy bear more pressure before relief will be given, and if casks are old, and thought'to lie-weak, the piece S should beturned` only to' give less pressure upon the'.Y

inner en d ofthe tube g/,fas it "will be--seen that frelief comes from the pressure of the contents of the cask the inner surface of thefilauge z, which,"wlien suiiici'entv to compress the eushioihra'z, relieves the inner end 'ofthe tnbeyfrom Regent on. the' i nner ond-pcf S, andA for the key g, aresthe threads cast 'upon'v as one of great. in cutting and fitting in and through the'openings o o, and'out at P.

i key c,- may allows the liquid to flow into the said tube at this When the cask l's suiiiciently relieved, the reaction of the cushion a: will close'thetube y upon itsseat on, S, and the flow will cease.' We call this an adjustable safety-bung. A

i' In considering tap,0, we find the permanent parts attached to the inside, while the key g is made readily detachable, and'notto' be brought in contact withthe eask until it is desired to draw from the contents within. V

This provision for' having thekey gvreadily removed, secures the cask against those' accidents .ofi-breaking or loosening the spigot, now so com mon when they are being rolled about, or piled one upon another, vas is generally the case in the ordinary transport-ation.

\In our arrangement, there are no projections from YtheY cash, te. bebruised er injured, erntet/anse lealnage .andwaste f The structureof this key-g is very simple,zhavingv threads on its spindle, to turn into the c ask, and openings o o, to letthe liquid flow into the tube', in its central portion, and in having thistube much enlarged in its outward end, for the purpose of allowing the insert-ion of a tube, of wood, leather, or other suitable yielding substance'.A (See g. 2.)- i

The object of the peculiar structureand combination of parts in this key g is to provide against the expense of a` separate stop-cock, as combined with a tap or bung; In other devices much fitting of screwthreads and a large amount of metal, involving great expense, were required, while the application of the 'tu-be of wood i, ih the key g, enables, one to turn in the simply-bent tube fr, with slight threads out on it, where it entersthe wood, and without ,expensive fitting. (See fig. 2.) l

We consider th' an important feature of our invenf tion, and improvementjin .the right direction, simple in strncture, and saving expense.' Thefoperation of this tap is as follows: v Turn thekey g in, when you woulddraw liquor from tlecask, and the inner end thereof will carry the cap d back against the spring f, relieving lthe closeoontaot upon the cushion at my, and the liquid is free to iiow N is a'packing around thespindleof the key Lto 'prevent'leakage at this point. f.

When, inl the manufa ture of thesev cask-heads, it may be thought the safety-'event' in bung B' may not be required, this bung, with its vent,.and the faucet O,

may be left off, and the bung B', the tap 0'," and the all'be combined in o nefand the saine article," nd thus answer the double purpose ofbung and fauc'et. (See iig. 5.)

Nith this arrangement, if any one, witl1 a v0f of ale 0r beer, or other 'f'ernientiug ilqnor, onz

hand, inds the too ardent fermentation is straining the casks, he can bring immediate relief by using the key y to draw oi' a.' -little of the contents. Any -key will fit the corresponding part in any tap.

It will be seen, from the manner already described., that the bent tube v may be easily detached from the key y, as, v vhen the cask stands on end, while its contents are being drawn off, this tu'befv would not be required. e

Our inyeution also relates to the construction of the detachable key g, and its use, either with or without the tube fu; r

. l Taps have heretofore been .tted in bungs, and made to use in connection with the ordinary stop-cock, which is always of much cost. (See Albert Hollowells patent, of June 20,1865.)A fWe especially disclaim all such, as their great expense could not be borne in use jupon the thousands or" beer, ale, and other casks, for

containing cheap beverages.

What we do claim as of our invention, "and desire to secure by Letters Patent, isl l. As anew article of manufacture, a. Cask-head, :is

described, that is, composed of the disk A, of castinetal, and having a biing-openingkvi'th' female screw moulded and cast therewith, and corresponding bung, with male screw cast in the same way.

The key g, constructed described, and used inf connection withthe tap C, or tap C', and bung B', for

the purposes specified. Q

3. The cfmnbination and arrangement of the -tap C with and upon the disk A, substantially as s et forth.
